A very good idea, seems quite easy to implement with a couple of tubings going from the electrolytic cell to the fuel cell, this reminded me I had seen similar bubbling of an external gas on an electrode in articles on reference electrodes ( see e.g.: http://en.wikipedia.org/wiki/Standard_hydrogen_electrode ). Reference electrodes are probably quite relevant to the present discussion, in that they seem capable to maintain a reference voltage as long as you keep bubbling the gas, without any additional energy input! > This looks like an interesting high school science project. Indeed, and it might even allow practical clean batteries for low power devices. Michel
